#+end_src

* SSH setup
** Generating a new SSH key
#+begin_src bash
  ssh-keygen -t rsa -b 4096 -C "dehaeze.thomas@gmail.com"
#+end_src

** Start the ssh-agent in the background
#+begin_src bash
  eval "$(ssh-agent -s)"
#+end_src

** Add the SSH key to the ssh-agent
#+begin_src bash
  ssh-add ~/.ssh/id_rsa
#+end_src

* GnuPG
https://gnupg.org/

** Install the gnupg package:
#+begin_src bash
  yay -S gnupg
#+end_src

** Create a key pair
#+begin_src bash
  gpg --full-gen-key
#+end_src

#+begin_src conf
  max-cache-ttl 60480000
  default-cache-ttl 60480000
#+end_src

* Launcher - Rofi
https://github.com/DaveDavenport/rofi

** Installation
#+begin_src bash
  yay -S rofi
#+end_src

** Setup rofi as a dmenu replacement
Setup rofi as a dmenu replacement in =~/.i3/config=:
#+begin_src
  bindsym $mod+d exec --no-startup-id rofi -show run
#+end_src

** Run sudo commands with rofi
https://github.com/DaveDavenport/rofi/issues/584#issuecomment-384555551

Use ~sudo -A~, that will open a rofi prompt to ask for the password.

For that to work, we need to add the following code to =~/.profile=:
#+begin_src bash
  export SUDO_ASKPASS=~/bin/askpass-rofi
#+end_src

The =askpass= script is:
#+begin_src bash
  #!/bin/sh

  # Take password prompt from STDIN, print password to STDOUT
  # the sed piece just removes the colon from the provided
  # prompt: rofi -p already gives us a colon
  rofi -dmenu \
       -password \
       -no-fixed-num-lines \
       -p "$(printf "$1" | sed s/://)"
#+end_src

* Password Manager: Pass
https://www.passwordstore.org/

** Install the pass package
#+begin_src bash
yay -S pass
#+end_src

** Initialize the password store as a git repository
#+begin_src bash
pass git init
pass git remote add origin https://github.com/tdehaeze/pass.git
#+end_src

** Gui Manager
https://github.com/IJHack/qtpass

#+begin_src bash
yay -S qtpass
#+end_src

** Integration with Rofi
https://github.com/carnager/rofi-pass

*** Installation
#+begin_src bash
  yay -S rofi-pass
#+end_src

Then we can add a shortcut to =rofi-pass= on i3 config.

*** Alternative
https://github.com/ibizaman/pass-clip

#+begin_src bash
  yay -S pass-clip
#+end_src

** Integration with Browsers
This is explained [[*Integration with Pass: the password manager][here]].

** Integration with Git
https://github.com/languitar/pass-git-helper
*** Installation
#+begin_src bash
  yay -S pass-git-helper
#+end_src

*** Configuration
First, add the relation between repository addresses and entries in =pass=. This is done in the following config file =.config/pass-git-helper/git-pass-mapping.ini=:
#+begin_src
[github.com*]
target=github.com/tdehaeze
#+end_src

Then, add the credential helper on the git configuration file =~/.gitconfig= and add the default username for the repositories adresses.
#+begin_src
[credential]
    helper = !pass-git-helper $@

[credential "https://github.com"]
    username = tdehaeze
#+end_src

** Integration with other programs
Integrate pass in other programs is usually very easy, here are few examples:
- =~/.msmtprc=:
  - =passwordeval "pass email/dehaeze.thomas@gmail.com"=
- =~/.mbsyncrc=
  - =PassCmd "pass email/dehaeze.thomas@gmail.com"=

* Bookmark Manager: Buku
https://github.com/jarun/Buku

** Installation
#+begin_src bash
  yay -S buku
#+end_src

** Integration with Rofi
https://github.com/carnager/buku_run

*** Installation
#+begin_src bash
wget https://raw.githubusercontent.com/carnager/buku_run/master/buku_run -o ~/bin/buku_run
chmod +x ~/bin/buku_run
#+end_src

*** Configuration
The configuration file is here: =~/.config/buku_run/config=

** Integration with qutebrowser
[[*Integration with Buku][Integration with Buku]]

** Synchronization with a git repository
The database is stored in =~/.local/share/buku/bookmarks.db=.

We initialize a git repository in this folder:
#+begin_src bash
cd ~/.local/share/buku/bookmarks.db
git init
#+end_src

Then we create a script that will automatically add =bookmarks.db= and push to some repository: =~/scripts/buku_git_push.sh=.

To automatically run the script every day, a systemd unit is used: =~/.config/systemd/user/bukugit.timer= and =~/.config/systemd/user/bukugit.service=

#+begin_src bash
systemctl start --user bukugit.timer
systemctl enable --user bukugit.timer
#+end_src

** Import Bookmarks from Firefox and Chrome
From Firefox, export the bookmarks as html file.
Then import the bookmark file using =buku -i bookmarks.html=.
This will add a tag with current date to all bookmarks imported.
To remove them, use: =buku --replace '2018dec20' ''=

** Web Interface
Run:
#+begin_src bash
bukuserver run --host 127.0.0.1 --port 5001
#+end_src

And then browse to http://127.0.0.1:5001.

** Cheatsheet
| Command      | Usage                  |

And enter is bound to =magic_enter= that directly sends the message if its one line, and if its multiple line, waits a little bit and then sends the message:
#+begin_src conf
  /key bind ctrl-M /input magic_enter
#+end_src

** Slack Integration
https://github.com/wee-slack/wee-slack

*** Installation
#+begin_src bash
  yay -S python2-websocket-client
#+end_src


#+begin_src bash
  cd ~/.weechat/python
  wget https://raw.githubusercontent.com/wee-slack/wee-slack/master/wee_slack.py

#+end_src

*** Add your Slack API key(s)
Log in to Slack:
#+begin_src conf
  /slack register
#+end_src
This command prints a link you should open in your browser to authorize WeeChat with Slack. Once you've accomplished this, copy the "code" portion of the URL in the browser and pass it to this command:

#+begin_src conf
  /slack register [CODE_FROM_URL]
#+end_src

Your Slack team is now added, and you can complete setup by restarting the wee-slack script.
#+begin_src conf
  /python reload slack
#+end_src

If you don't want to store your API token in plaintext you can use the secure features of weechat:
#+begin_src conf
  /secure passphrase this is a super secret password
  /secure set slack_token [YOUR_SLACK_TOKEN]
  /set plugins.var.python.slack.slack_api_token ${sec.data.slack_token}

* Theme manager
The idea would be to have a command that changes the theme of all the system.

There would be at least one light and one dark theme.
Applications that could change:
- [ ] terminal: https://github.com/khamer/base16-termite. TODO: this does not seems to work. Some is takken from config of termite, some from xresources. Also when reload the terminal is does not make the colors well: https://github.com/thestinger/termite/issues/273
It seems the color is due to this part of the script. Should then source this file somehow.

#+begin_src bash
BASE16_SHELL="$HOME/.base16-manager/chriskempson/base16-shell/"
[ -n "$PS1" ] && \
    [ -s "$BASE16_SHELL/profile_helper.sh" ] && \
        eval "$("$BASE16_SHELL/profile_helper.sh")"
#+end_src

- [X] shell: https://github.com/chriskempson/base16-shell
- [X] ranger: uses colors of the shell
- [X] vim: https://github.com/chriskempson/base16-vim
- [ ] emacs: https://github.com/belak/base16-emacs
- [X] zathura: https://github.com/nicodebo/base16-zathura
- [ ] neomutt: https://github.com/josephholsten/base16-mutt
- [X] ncmpcpp: uses colors of terminal (termite) defined in =~/.config/termite/config=
- [X] polybar: uses colors of Xresources: =~/.Xressources.d/colors=
- [ ] dunst: https://github.com/khamer/base16-dunst
- [ ] fzf: https://github.com/nicodebo/base16-fzf
- [ ] i3: https://github.com/khamer/base16-i3
- [ ] qutebrowser: https://github.com/theova/base16-qutebrowser
- [ ] rofi: https://gitlab.com/0xdec/base16-rofi
- [ ] background: use custom script
- [ ] tmux
- [ ] GUI file manager?

Possible theme managers:

- https://github.com/dylanaraps/pywal

** Base16
https://github.com/chriskempson/base16
http://chriskempson.com/projects/base16/
https://www.youtube.com/watch?v=QcOxU1sOOuw

*** Base16 Philosophy
Define colors according to rules: http://chriskempson.com/projects/base16/
Then we can use these colors multiple applications.

*** Base16-shell
https://github.com/chriskempson/base16-shell

This changes the shell colors. This should be added to =~/.bashrc=:
#+begin_src bash
# Base16 Shell
BASE16_SHELL="$HOME/.config/base16-shell/"
[ -n "$PS1" ] && \
    [ -s "$BASE16_SHELL/profile_helper.sh" ] && \
        eval "$("$BASE16_SHELL/profile_helper.sh")"
#+end_src

*** Base16-manager
https://github.com/AuditeMarlow/base16-manager

This help changes many applications colors at once.
